I only ever jerked off at work (not the men's room) after hours. Work gets boring when you're the last one left in the office and sometimes taking it out for a breather is better than caffeine. I think that if you check my desk with UV light you'll find me guilty of many occasions of pleasure. (Can't cum on the floor as it's carpeted.)

As for the men's room, I've done it there more times than I care to remember. At the urinal. In the cubicle. Stark naked in the men's room after hours.

I love jacking off at work, but then, I love jacking off anywhere I can . I've done it in the men's room many times as well as in my office and other people's offices (after hours) including one of the partners, where I stroked off sitting behind his desk and on his couch. I've also jacked off in the garage, again after hours.

I had an online fuck buddy who would call me at work and urge me to jack off with him. Very hot. It was pretty risky since there is a glass panel to the side of my office door. Jacked under my desk. My buddy was often in his car, which he pulled over to the side of road to jack with me.

Not at my place of work but I had a mate who managed a souvenirs shop next to the Tower of London, selling rubbish souvenirs to the gullible. One night, at closing time, he locked up the shop and we had a good wank together between two of the racks of shelves. When he came he picked up a woolly hat off the display and wiped his cock on it. I presume that he threw it away afterwards - I least I hope that he did! It was very horny knowing that tourists were walking past the window a few feet away.
